Here's the wiki for a well-known paradox that Robert's Rules of Order might lead to in case of a tied vote on a motion (i.e. as a group, to eat a bale of hay A instead of a bale of hay B, both equally distant):

The only way out of the impasse, I can see, with Robert's Rules of Order, is for someone to think to make a motion to decide which bale to eat based on the flip of a coin. Then the motion likely passes unanimously, and the problem is solved.
